Description

图像处理的方法、装置和系统 技术领域
本发明涉及图像技术应用领域，具体而言，涉及一种图像处理的方法、装置和传输系统。
背景技术
在现有的发光二极管(Light Emitting Diode，简称LED)显示技术中，在大屏显示场景下，特别是拼接屏的无缝拼接场景下，超长显示应用广泛，由于LED显示屏的任意延展性，实现了超长无缝拼接，但是对于超长显示，这对播放器的分辨率的要求更高。
现有LED显示系统包括：多媒体播放盒，现场可编辑逻辑门阵列(Field Programmable Gate Array，简称FPGA)发送卡，FPGA接收卡和LED显示屏，其中，多媒体播放盒由应用处理器、内存、存储和安卓(Android)系统组成，安卓系统用于对播放的多媒体文件进行播放解码和对显示效果的渲染，以使得提供高质量的画面。这里在多媒体播放盒的输出端，通过LCD显示控制器(LCD Controller，简称LCDC)对安卓系统渲染后的图像数据进行时序转换，由RGB接口发送至FPGA发送卡，由FPGA发送卡对时序转换后的图像数据进行解析，保存有效数据，并通过以太网传输给FPGA接收卡，从而由FPGA接收卡驱动LED显示屏进行显示。
但是由于多媒体播放盒中应用处理器自身分辨率的限制，导致应用处理器输出的图像数据通过FPGA发送卡发送至FPGA接收卡，最终由LED显示屏显示时，由于带载的限制，导致无法显示高分辨率的图像。
在相关技术中，对于一些廉价的多媒体播放盒不能做到超长的带载，因为多媒体播放盒上的芯片性能限制无法输出超长的分辨率视频信号，但是对于超长显示的场景，客户使用可带载更长的播放盒成本又高，低成本的播放盒是不能满足实际要求的。

图1是根据本发明实施例一的图像处理的方法的示意图，如图1所示，在多媒体播放盒侧，该方法包括如下步骤：
步骤S102，依据第一分变率对待传输数据进行处理，得到第一图像数据，其中，第一图像数据中每行图像数据所表征的图像分辨率为第一分辨率，第一分辨率为系统设置的最大分辨率；
在步骤S102中，在本申请实施例提供的图像传输方法中可以适用于多媒体播放盒，其中，多媒体播放盒是由安卓系统、应用处理器，显示控制器，发送卡，CPU内其他模块，内存和存储组成，图2是根据本发明实施例一的图像处理的方法中多媒体播放盒的示意图，如图2所示，在本申请实施例中内存标记为双倍速率同步动态随机存储器(Double Data Rate，简称DDR)，存储标记为嵌入式多媒体卡(Embedded Multi Media Card，简称EMMC)，显示控制器标记为(LCD drive controller，简称LCDC)，发送卡标记为现场可编辑逻辑门阵列(Field Programmable Gate Array，简称FPGA)发送卡。
多媒体播放盒依据第一分变率对待传输数据进行处理，得到分辨率为第一分辨率的图像数据(即，本申请实施例中的第一图像数据)，其中，通过在安卓系统中的帧缓冲区设置最大分辨率，将待传输数据以最大分辨率进行渲染处理，得到分辨率为第一分辨率的图像数据。
例如，常规安卓系统内部分辨率只支持1920×1080，但是在帧缓冲区可以按照3840×540来渲染处理，因此，通过设置最大分辨率，将待传输数据由分辨率为1920×1080渲染为分辨率3840×540的图像数据，其中，3840×540为本申请实施例提供的第一分辨率，1920×1080为本申请实施例中的第二分辨率。
需要说明的是，本申请实施例中待传输数据可以为图像数据，其中图像数据包括：文字、除文字外的人物、风景、卡通等图片、视频。
步骤S104，对第一图像数据进行折叠处理，得到第二图像数据，其中，第二图像数据的行数大于第一图像数据，第二图像数据中每行图像数据所表征的图像分辨率为第二分辨率，第二分辨率小于第一分辨率。
在步骤S104中，多媒体播放盒通过LCDC将步骤S102中得到的第一分辨率的待传输数据进行处理，得到第二图像数据，其中，二图像数据的行数大于第一图像数据，第二图像数据中每行图像数据所表征的图像分辨率为第二分辨率，第二分辨率小于第一分辨率。
可选的，第二图像数据中每n行图像数据所表征的图像分辨率之和等于第一分辨率，其中，n为大于等于2的正整数。
例如，由于LCDC只支持1920×1080，为了实现超长显示，图3是根据本发明实施例一的图像处理的方法中将第一分辨率拆分为第二分辨率的示意图，如图3所示，多媒体播放盒的LCDC将分辨率为3840×540的待传输数据拆成两行分辨率为1920×1080的图像数据，其中LCDC在拆分分辨率为3840×540的待传输数据时，为了确保待传输数据在显示时的正确，LCDC按照时序对原分辨率为3840×540的待传输数据进行拆分，得到两行分辨率为1920×1080的图像数据；
由于在LED显示屏上显示画面是由多行图像数据组成的，因此在对每行分辨率为3840×540的待传输数据进行处理时，均拆分为两行分辨率为1920×1080的图像数据，以使得在显示设备显示时由显示设备对待传输图像进行还原，将两行分辨率为1920×1080的图像数据合并为一行分辨率为3840×540的待传输数据，从而实现超长显示。
在本发明实施例中，通过依据第一分变率对待传输数据进行处理，得到第一图像数据，其中，第一图像数据中每行图像数据所表征的图像分辨率为第一分辨率，第一分辨率为系统设置的最大分辨率；对第一图像数据进行折叠处理，得到第二图像数据，其中，第二图像数据的行数大于第一图像数据，第二图像数据中每行图像数据所表征的图像分辨率为第二分辨率，第二分辨率小于第一分辨率，达到了通过普通的媒体播放盒实现超长带载的目的，从而实现了降低设备成本的技术效果，进而解决了由于相关技术中媒体播放盒上的芯片性能限制无法输出超长的分辨率视频信号，使用可带载更长的播放盒成本又高，导致的普通媒体播放盒无法满足超长显示需求的技术问题。
可选的，步骤S102中依据第一分变率对待传输数据进行处理，得到第一图像数据包括：设置帧缓冲区的分辨率为第一分辨率；依据第一分辨率对待传输数据进行图层叠加，得到第一图像数据；将第一图像数据存储至帧缓冲区。
进一步地，可选的，依据第一分辨率对待传输数据进行图层叠加，得到第一图像数据包括：获取至少两帧待传输数据；将至少两帧待传输数据中的每行图像数据依据第一分辨率进行图像渲染，得到每行图像数据所表征的图像分辨率为第一分辨率的第一图像数据。
可选的，步骤S104中对第一图像数据进行折叠处理，得到第二图像数据，具体包括：获取第一分辨率的长的1/n，和第一分辨率的高的n倍，得到第二分辨率；依据第二分辨率对第一图像数据进行提取，得到所表征的图像分辨率为第二分辨率的第二图像数据；或者，获取第一分辨率的高的1/n，和第一分辨率的长的n倍，得到第二 分辨率；依据第二分辨率对第一图像数据进行提取，得到所表征的图像分辨率为第二分辨率的第二图像数据。
在一种可选的实时方式中，图4是根据本发明实施例一的图像处理的方法中分辨率翻倍后折半输出的示意图，如图4所示，在本申请实施例中，安卓系统以版本为android5.1为例进行说明，通过设置android系统帧缓冲区(frame buffer)的分辨率为3840×540，上层的图层合成单元(SurfaceFlinger)按照framebuffer分辨率的3840×540大小对图像进行渲染和处理(例如，图层叠加)，然后将渲染好的一帧图像存到帧缓冲中(例如，显存)，接下来LCDC对帧缓冲中的数据按照framebuffer分辨率长的一半和高的两倍产生时序(1920×1080)的待传输数据。
基于上述，如图3所示，假设芯片本身只能最大输出1920*1080的分辨率，将处理好的3840*540的图像数据进行折叠输出(仅以一行为例进行说明)。
可选的，本申请实施例提供的图像处理的方法还包括:
步骤S106，将第二图像数据中每n行图像数据进行拼接处理，还原为第一图像数据，并发送还原后的第一图像数据。
进一步地，可选的，步骤S106中将第二图像数据中每n行图像数据进行拼接处理，还原为第一图像数据,具体包括：将第二图像数据中每行图像数据中的有效数据存储至内存；将每行图像数据中的有效数据依据预设行关系进行获取，得到至少一组n行互相关联的有效数据；将每组n行互相关联的有效数据合为一行，还原得到所表征的图像分辨率为第一分辨率的第一图像数据。
可选的，将每组n行互相关联的有效数据合为一行，具体包括：获取第二分辨率的长的n倍和高的1/n，得到第一分辨率；根据第一分辨率对每组n行互相关联的有效数据进行提取，得到所表征的图像分辨率为第一分辨率的一行图像数据；或者，获取第二分辨率的长的1/n和高的n倍，得到第一分辨率；根据第一分辨率对每组n行互相关联的有效数据进行提取，得到所表征的图像分辨率为第一分辨率的一行图像数据。
在步骤S106中，基于步骤S104得到的第二图像数据，如图2所示，通过FPGA发送卡将第二图像数据进行还原，即，将两行第二图像数据合并为一行分辨率为第一分辨率的图像数据，并将该第一分辨率的图像数据发送至显示设备，以使得显示设备根据该分辨率为第一分辨率的图像数据实现超长显示。
例如，FPGA发送卡采集LCDC输出的两行1920×1080的图像数据，按照两行两行采集，将两行采集的1920个像素点拼成3840个像素点，实现了分辨率翻倍的效果和 功能。
综上，结合步骤S102至步骤S106，本申请实施例提供的图像处理的方法，可以适用于超长显示场景，例如，银行窗口上方的长条LED显示器，由于现有的超长显示都会受到原多媒体播放盒本身带载的限制，即，长度只能带载1920像素点的播放器只支持显示1920像素点，从而限制LED显示屏的显示长度，因此现有技术的为了克服这点智能使用成本高可带载更长的多媒体播放盒，而无法有效解决在固定带载的情况下如何实现超长显示。
在一种可选的实时方式中，FPGA发送卡接收到的视频信号是1920*1080的待传输数据，但是该1920*1080的待传输数据为3840*540折叠的待传输数据，FPGA实现接收第一行待传输数据将有效数据信号保存到内存中，再连续将第二行的待传输数据的有效数据存到内存中，将两行信号拼接在一起实现一行为3840个像素点，第三行、第四行依次相同处理。最后发送卡将还原的分辨率为3840*540的待传输数据通过以太网传输给接收卡并进行显示。
需要说明的是，本申请实施例提供的图像处理的方法仅以通过以太网传输为优选示例进行说明，除此之外还支持局域网传输，短距离传输等方式将还原为第一分辨率的待传输数据传输至显示设备，以实现本申请实施例提供的图像传输方法为准，具体不做限定。
本申请实施例提供的图像处理的方法通过在安卓系统设置最大分辨率，使得原支持长度为1920像素点的多媒体播放器，将待传输数据通过帧缓冲区按照最大分辨率进行渲染处理，得到长度为3840像素点的待传输数据，但是由于多媒体播放器的LCDC只支持长度为1920像素点的数据提取和时序转换，为了确保长度为3840像素点的待传输数据能够顺利输出，将该长度为3840像素点的待传输数据拆分为两行长度为1920像素点的数据，从而克服由于硬件设备的带载限制，导致的LED显示屏显示受限的问题。
由于在LCDC拆分为了两行长度为1920像素点的数据，为了在LED显示屏(即，本申请实施例中的显示设备)实现超长显示，通过FPGA对两行长度为1920像素点的数据进行合并，得到长度为3840像素点的待传输数据，并将长度为3840像素点的待传输数据发送至显示设备，以此实现分辨率翻倍的效果，和LED超长显示的功能。
需要说明的是，本申请实施例中仅以芯片支持分辨率1920×1080的多媒体播放盒为例进行说明，此外，芯片支持分辨率4096×2160(即，4K画质)的多媒体播放盒同样适用于本申请实施例提供的图像处理的方法，若使用本申请实施例提供的图像处理 的方法，则可以提升至分辨率8192×1080，因此本申请实施例提供的图像处理的方法仅以上述为例进行说明，以实现本申请实施例提供的图像处理的方法为准，具体不做限定。
